LAMP.

SPECIFICATION forming part of Letters ,Patent No.- 224,449, datedFebruary 10, 1880.

Application filed January 13, 1880.

To all whom it may concern Be it known that I, RIGHAR O. LAWTON, ofWaterbury, in the county of New Haven I and State of Connecticut, haveinvented a new Improvement in Lamps andI do hereby de-' clare thefollowing, when taken in connection with the accompanying drawing andthe-letters of reference marked thereon, to be a full, clear, and exactdescription of the same, which said drawing constitutes part of thisspecification, and represents aside view, partly in section.

This invention relates to an improvementin lamps, with special referenceto the standard endof the standard a socket, G, is formed to receive apiece of cork or any similarly-compressible material,'D, and in or ontothis socket a cap, E, is screwed, to bear upon the material D so.as tocompress it in the socket. -Vertically through the cap and material is aperforation, corresponding to a rod, a, attached to the lamp-fount, andadapted to be moved up and down through the com pressed material D,which produces sufficient friction on the rod to support the fount atany desirable elevation, and this friction may be increased ordiminished by turning the screw-cap E accordingly.

The standard may be constructed so that when the fount is in its lowestposition, as in dicated in broken lines, the spindle will be entirelyhidden, or the standard may be made in telescopic form, so that at alltimes the spindle will be hidden. This adjustment holds the lamp in avertical central line over the spindle, avoiding the one-sided conditionof the student-lamp, and

consequent needful weighting of the base, and the construction ischeaper, more convenient, and equallyserviceable and desirable.

The arrangement of the parts may be reversed-that is to say, the socketmay be attached to the'fount and the spindle to the base; but thearrangement as described is preferable.

I claim;-

The combination of the fount andbase of a lamp with the Socket 0,compressible material D, and cap E-on one part, and the spindle a on theother part, substantially as described.
